A user with administrator privileges can alter the default setting with a command like this (setting it to 30000 milliseconds, or 30 seconds): Single Server: registry_set ('fct_timeout_max', '30000')
Cluster:
cl_exec ('registry_set (''fct_timeout_max'', ''30000'')') ---++Related * [[VirtTipsAndTricksGuide][Virtuoso Tips and Tricks Collection]] * [[VirtFacetBrowserInstallConfig][Installation and Configuration of the Virtuoso Facet Browser]] * [[http://docs.openlinksw.com/virtuoso/virtuosospongerfacent.html#virtuosospongerfacentuirestapi][Virtuoso APIs for Faceted REST services]]
